I used the temp sensor that was a match for the cluster and turned the threads down to match the LS head

When I did my swap I used the LS sensor on teh drivers side head for the ECM input and removed the plug on the passenger side head to install the sensor for the cluster. When I had the plug out I just matched the threads I cant remember the size. I know it is smaller then the 91-90 factory sensor for sure
